<p>The step comprises a general configuration with an external outline profile in a triangle-rectangle shape wherein the hypotenuse coincides with the major support face, the major cathetus with the horizontal face and the minor cathetus with the vertical face, and is characterized in that the major support face (1) of a step includes fastening elements complemented during stacking, by other major support face (1) fastening elements of another identical step. This results in the stable stacking of pairs of steps in contact through their major faces and forms a prismatic block predetermined by said two identical steps, thus providing advantages for their handling, both in the manufacturing process and during transport and assembly.</p> |
